Can neural therapy help solve my lower back pain problems?

May help. Depends on what therapy is used on what pain. Diagnostic blocks followed by radio frequency lesioning may work on facet joint related low back pain.
Possibly. Neural therapy works well for soft tissue problems, especially if they are acute. However, back problems can also be due to many other factors. If a disc is involved, discosan is the best therapy. There is also the question of why you are getting back pain. Underlying infections and other causes must be determined and corrected to get long lasting relief.
